使用 httpclient 在 C# 中获取 API 数据

Question

我刚刚开始使用 API，并且完全公开......我从这个答案复制并粘贴：How do I make calls to a REST api using c#? 但很明显我迷路了。

我试图从 Dropbox api 获取信息开始简单。

我插入了 api URL，但我不知道如何传递身份验证令牌或帐户 ID。

private const string URL = "https://api.dropboxapi.com/2-beta-2/users/get_current_account";
        private const string urlParameters = "access_token=xxxxxxxxxxxxx";

        static void Main(string[] args)
        {
            HttpClient client = new HttpClient();
            client.BaseAddress = new Uri(URL);

            // Add an Accept header for JSON format.
            client.DefaultRequestHeaders.Accept.Add(
            new MediaTypeWithQualityHeaderValue("application/json"));

            // List data response.
            HttpResponseMessage response = client.GetAsync(urlParameters).Result;  // Blocking call!
            if (response.IsSuccessStatusCode)
            {
                // Parse the response body. Blocking!
                var dataObjects = response.Content.ReadAsAsync<IEnumerable<DataObject>>().Result;
                foreach (var d in dataObjects)
                {
                    Console.WriteLine("{0}", d.Name);
                    Console.ReadKey();
                }
            }

来自 Dropbox 的 http 请求应该是：

POST /2-beta-2/users/get_account
Host: https://api.dropboxapi.com
User-Agent: api-explorer-client
Authorization: Bearer xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx-xxxxxxxxxxxxxxxx
Content-Type: application/json

{
    "account_id": "dbid:xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
}

Answer 1

您可能需要将 Bearer 令牌添加到请求中的 Headers 中

client.DefaultRequestHeaders.Add("Authorization", "Bearer " + accessToken);
